Pulseaudio doesn't come up after plugging out external sound device

Jaizkibel · January 23, 2021, 2:49pm

Hi,

I used to have a Audient ID4 external USB sound device plugged in one of my USB slots.
Now I have plugged it out to use it with my laptop.

But now pulseaudio doesn’t start up, neither automatically nor manually, since pulse keeps looking for the accustomed usb device, as I read in the journal:

(the aforementioned device is referred to as “hw:iD4”)

.

I guess there is a file somewhere, where the iD4 is listed and simply needs to be uncommented or something like that. But where do I find it?

Thanks in advance.

Now it’s fine. I don’t know exactly what helped. Either it was changing the default sound card in QjackCtl, or simply killing jackd. But after rebooting PA was back again.
